Geometry

Some tips:

• As you follow along in Ansys, you can switch between the video and Ansys easily using Alt+Tab if you are on a MS Windows computer.
• In newer Ansys versions, there is a new Sketch tab in SpaceClaim with slight changes in the sketching procedure which you should be able to able to figure out with a bit of poking around.  
• In SpaceClaim, you can zoom in/out using the mouse wheel, rotate using MMB (middle mouse button) and translate using Ctrl+MMB.

Geometry

Set Up

First, we need to specify that the geometry is 2-dimensional. Right click the Geometry box Image Removed and select Properties. This will open the Properties of Schematic A2: Geometry Window. Under Advance Geometry Options change Analysis Type from 3D to 2D.

...

After the analysis type has been set, we are ready to launch Design Modeler, the design tool in ANSYS. Open Design Modeler by double clicking the geometry box Image Removed. After launching the Design Modeler, you will be prompted to choose a standard unit of measurement. Select Meter as the standard unit, and click OK.

Sketching

We want to sketch on the XY plane. To look at the XY plane, click the positive Z-Axis on the compass in the Graphics window.

...

To begin sketching, click on the Sketching tab in the Tree Outline window. To draw our domain, we will use the Rectangle tool. Click on Image Removed in the Sketching Toolboxes window. In the graphics window, draw the rectangle by first clicking on the origin (make sure the P icon is showing, meaning you are in fact selecting the point), then select a point in the 1st quadrant.

...

Next, we need to create another rectangle, adjacent to the first. To accomplish this, we will use a 3-point triangle. Select the rectangle from 3 points tool Image Removed from the sketching tool bar. Next, select the three points specified below. This will create a second rectangle in the graphics window.

Now, we need to draw the wedge outline in the geometry. We will use the line tool to create the wedge. Select the line tool in the Sketching Toolboxes window. Image Removed

Now, we need to remove the extraneous lines that we created. In the Sketching Toolboxes window, click the Modify tab, and select Image Removed. Next, trim the lines indicated by the figure below

The final sketch should look like the image below

Dimensions

Next, we need to add the dimensions for the geometry. In the Sketching Toolboxes window, select the Dimensions tab. Next, select the general dimensioning tool Image Removed. To create a dimension, you first select a line. This will create a dimension for that line. Next, you will need to place the dimension next to the line. See the image below for guidance.

Next, create dimensions for the following 5 lines:

In order to add magnitudes to the dimensions, look to the Details window. You will see 5 dimensions that have been specified. Click on a dimension magnitude, and notice that the corresponding dimension will be highlighted in the graphics window. Use the following diagram to add the dimensions to the geometry.

When the dimensions have been correctly applied, the geometry should look like this:

Create Surface

Next, we need to create a surface from the sketch. In the menu tool bar, select Concept > Surface from Sketches. In the graphics window, select and line of the sketch. Next, in the details window, select Geometry > Apply. Finally, press Image Removed. The final geometry should look like the figure below.

Now that we have completed the geometry. Save the project, and close the Design Modeler.
